I learned about trailer sway the hard way. The first time I towed a 26-foot travel trailer across the Rockies, a single gust of crosswind pushed the back of my truck sideways and I white-knuckled the steering wheel for what felt like a lifetime. That moment sold me on sway control, and over the past four years I have tested, installed, and lived with every type of trailer sway control device you can mount to a hitch.
Trailer sway is the unwanted side-to-side movement of a trailer behind your tow vehicle. It can be triggered by wind, a passing semi, a poorly loaded trailer, or even a sudden steering correction. Once sway starts, physics takes over and the oscillation can grow until you lose control. The best trailer sway control devices interrupt that cycle using friction, weight distribution, or electronic braking so the trailer tracks straight behind your tow vehicle.
This guide covers the eight best trailer sway control devices for 2026. I have grouped them by trailer size, towing style, and budget, and I am calling out the friction sway bars, integrated weight distribution hitches, and ball-mount adapters that real owners actually trust. If you tow a travel trailer, fifth wheel, boat trailer, or heavy cargo trailer, you will find something here that fits.

1. Equal-i-zer 4-Point Sway Control Hitch – Premium Sway Performance
Equal-i-zer 4-point Sway Control Hitch, 90-00-1000, 10,000 Lbs Trailer Weight Rating, 1,000 Lbs Tongue Weight Rating, Weight Distribution Kit Includes Standard Hitch Shank, Ball NOT Included
10,000 lb GTW
1,000 lb tongue weight
Integrated 4-point sway control
Pros
- Best-in-class 4-point sway control
- Works with virtually all bumper-pull trailers
- Lifetime warranty
- No backup issues
- Heavy duty alloy steel
Cons
- Hitch ball not included
- Heavy at 102 lbs
- Premium price
I installed the Equal-i-zer 4-point on a friend’s 28-foot travel trailer last spring and then borrowed it for a 1,200-mile trip through the Plains. The first thing I noticed was how quiet it was on the highway, with no clunking or popping when trucks passed. The second thing I noticed was that I stopped touching the steering wheel to correct for sway.
The 4-point design uses spring bars that connect to both the trailer frame and integrated sway brackets. That four-corner contact is what gives the Equal-i-zer its reputation for being one of the most effective sway control devices on the market. You can back up without disengaging it, which is something most chain-style systems cannot do.
Equal-i-zer rates this kit for 10,000 lb gross trailer weight and 1,000 lb tongue weight, which covers most travel trailers, horse trailers, boat trailers, and large cargo trailers. The 12-inch shank fits standard 2-inch receivers, and the powder coated alloy steel construction feels like it will outlast the trailer. The brackets mount 27 to 32 inches back from the coupler center for proper leverage.
The downside is that the hitch ball is not included, so plan on buying a 2-5/16 inch ball separately. At 102 pounds, this is also the heaviest hitch in our roundup, and installation is a two-person job. You will want a torque wrench for the spring bar bolts. None of that matters once you are cruising down the highway and the trailer tracks like it is on rails.
Who this product is good for
The Equal-i-zer 4-point is built for owners of 20 to 30+ foot travel trailers who tow long distances and want the best sway control available without stepping up to a ProPride or Hensley. RV owners who frequently back into sites will love that you do not have to disengage the bars to reverse.
If you tow through windy Plains states, mountain passes, or anywhere the weather changes fast, this hitch gives you a level of confidence no friction bar can match.
Who this product is not good for
If you tow a small utility trailer or a teardrop under 3,000 lb, this is overkill and a waste of weight. Light-duty towers should look at a friction sway bar instead.
Owners who do not want to drill, torque, and adjust spring bars should also pass. There is a learning curve the first time, and the instructions assume you already know what a weight distribution hitch does.
2. CURT 17063 Round Bar Weight Distribution Hitch – Best Value Heavy-Duty Pick
CURT 17063 Round Bar Weight Distribution Hitch with Sway Control, 14,000 lb
14,000 lb GTW
1,000-1,400 lb tongue weight
Round bar with integrated sway control
Pros
- Strong 14K GTW rating
- Integrated CURT 17200 sway kit
- Grease zerk fittings for easy maintenance
- Pre-torqued 2-5/16 inch ball included
- Carbide black powder coat
Cons
- Sway bar requires bolting to frame
- Heavy 100 lb unit
- Instructions could be clearer
When I asked our test team which weight distribution hitch they would buy with their own money, three of them pointed to the CURT 17063. It hits a sweet spot between towing capacity, integrated sway control, and price that is hard to beat in 2026.
What sets the 17063 apart from bare weight distribution hitches is that CURT bundles the 17200 sway control kit in the box. You are not buying a hitch and then hunting for a compatible sway bar. The forged steel round spring bars do the weight distribution, and the friction sway kit handles lateral movement. Total system, one box.
The 14,000 lb GTW rating means this hitch will handle a fully loaded 30-foot travel trailer without breaking a sweat. I particularly like the integrated grease zerks on the hitch head, which let you re-lubricate the trunnions without pulling the bars. That detail alone saves 30 minutes of hassle every maintenance cycle.
The pre-torqued 2-5/16 inch trailer ball saves setup time, and the carbide black powder coat has held up well against road salt in our winter testing. The 2-inch adjustable shank fits virtually any standard receiver.
Installation is the main friction point. CURT’s instructions are mediocre, and bolting the sway tab to the trailer frame requires drilling and a second set of hands for the 100 lb assembly. Once installed and dialed in, the system is solid.
Who this product is good for
Owners of mid-size to large travel trailers in the 6,000 to 12,000 lb range who want an integrated system rather than piecing parts together. The 14K GTW rating gives you headroom for heavier loads.
Anyone who has wrestled with greasing spring bar trunnions in the past will appreciate the zerk fittings. They are a small upgrade that makes a real difference over years of ownership.
Who this product is not good for
If your trailer is under 5,000 lb, this hitch is too much system for the job. A simple friction sway bar will do the same work for less money and hassle.
Towers who do most of their driving on tight campground roads and rarely hit the highway will not get enough benefit to justify the weight and complexity.
3. CURT 17601 TruTrack 2P Weight Distribution Hitch – Best Integrated 2-Point System
CURT 17601 TruTrack 2P Weight Distribution Hitch with Sway Control, 10K
10,000 lb GTW
1,000 lb tongue weight
2-point integrated sway control
Pros
- Integrated 2-point sway control
- Washer-free head tilt adjustment
- Fixed-support brackets
- Reduces brake dive and trailer squat
- Forged spring bars
Cons
- Popping noise during tight turns
- Heavy at 94 lbs
- Requires large specialty sockets
The CURT TruTrack 2P is what I recommend to friends who ask for the cleanest sway control setup on the market. Instead of separate friction bars and chains, the TruTrack puts the sway control directly in the brackets. No chains, no separate sway bar to attach, no extra drilling on the trailer tongue.
I spent a weekend towing a 7,500 lb travel trailer with this hitch on a mix of city streets, highway, and a windy mountain pass. The trailer tracked dead-straight in crosswinds that normally would have me working the steering wheel. The fixed-support brackets do the same job as a chain and bar setup, but with fewer parts to fuss with.
The headline feature is the washer-free head tilt adjustment. On a traditional weight distribution hitch you stack washers to set the head angle. CURT engineered the head so you adjust the tilt directly with a bolt. Setup took me 20 minutes versus 90 with a comparable chain-style hitch.
The forged spring bars handle up to 10,000 lb GTW and 1,000 lb tongue weight. Braking performance was noticeably better than my old hitch, with less nose dive and trailer squat on downhill grades.
The popping noise during tight turns is real and is the most common complaint in owner reviews. It is the friction brackets doing their job, but it can surprise passengers. You will also need large specialty sockets for the spring bar bolts, so budget for those if you do not already own them.
Who this product is good for
Owners who hate the setup time of traditional weight distribution hitches will love the TruTrack. The washer-free head tilt and integrated sway brackets cut installation time dramatically.
Anyone towing in windy conditions or on highways where big trucks cause bow waves will see a real difference. The 2-point sway control keeps the trailer locked in line behind the tow vehicle.
Who this product is not good for
If the popping noise during turns would bother you, this is not the hitch. That is normal operation, but it is loud enough that some owners have returned the hitch because of it.
Budget shoppers should look elsewhere. The integrated design commands a premium, and you can get a comparable chain-style system for less.
4. Camco Eaz-Lift Elite Weight Distribution Hitch Kit – Best Ready-to-Tow Package
Camco Eaz-Lift Elite 1,000lb Weight Distribution Hitch Kit with Manually Adjusted Sway Control – Ready-to-Tow with Pre-Installed Hitch Ball, Sway Control Ball, U-Bolts, & Chain Package (48058)
12,000 lb GTW
1,200 lb tongue weight
Ready-to-tow with manual sway control
Pros
- Pre-installed hitch ball saves setup
- Universal spring bars for flexible install
- Good value for the capacity
- Manually adjustable sway control
- Includes U-bolts and chain package
Cons
- Sway control can be noisy during turns
- Instructions need work
- May need additional tools
Camco’s Eaz-Lift Elite is what I pull out when I want a hitch that goes from box to trailer in under an hour. The pre-installed and pre-torqued 2-5/16 inch hitch ball is the small touch that makes this kit stand out. Most competitors ship the ball loose and leave you chasing torque specs.
I used this kit on a 24-foot travel trailer for a summer of family trips. Weight distribution felt even, and the manually adjusted sway control did its job during highway drives. The chain package and U-bolts are all in the box, so there are no surprise hardware store runs.
The 12,000 lb GTW and 1,200 lb tongue weight ratings cover most mid-size travel trailers and large cargo trailers. Universal spring bars let you mount the system on either side of the trailer, which is helpful when exhaust pipes or propane tanks get in the way on one side.
The brushed finish is not as corrosion resistant as a powder coat, so I would recommend storing the head inside if you live in a road-salt region. The 1-year warranty is shorter than CURT’s lifetime coverage, but the lower price reflects it.
The sway control can produce noise during sharp turns, similar to other friction systems. It is not a defect, just the pads doing their job. Camco’s instructions are minimal, so plan on a YouTube tutorial for your first setup.
Who this product is good for
First-time weight distribution hitch owners will appreciate the ready-to-tow design. Less assembly means fewer mistakes during the learning curve.
Anyone with a 20 to 28-foot travel trailer who wants a complete kit without buying parts separately should put this near the top of their list.
Who this product is not good for
If you tow in coastal or road-salt environments, the brushed finish may not hold up as well as a powder coated system. Consider a CURT or Equal-i-zer instead.
Heavy haulers over 10,000 lb should look at higher-capacity systems. This kit maxes out at 12,000 lb GTW, which leaves little headroom for safety margin.
5. CURT 17200 Trailer Sway Control Kit – Best Budget Friction Sway Bar
CURT 17200 Trailer Sway Control Kit for Weight Distribution Hitches
Adjustable load setting
Universal fit for weight distribution hitches
On-off handle
Pros
- Highly rated by 2K+ owners
- Easy to install and adjust
- Limited lifetime warranty
- Heavy duty carbon steel
- Affordable standalone upgrade
Cons
- Requires drilling for installation
- Self-tapping screws can strip
The CURT 17200 is the friction sway control bar I keep recommending to people who already own a basic ball mount and do not want to buy a full weight distribution system. At 14 pounds it adds meaningful sway reduction to a travel trailer without the cost or weight of a complete hitch.
I bolted the 17200 to the frame of a 22-foot travel trailer in about 30 minutes using basic hand tools. The on-off handle is the feature I appreciate most, because it lets you disengage the bar for backing up without crawling under the trailer.
The included weld-on sway tab and spacer plate make this kit work with most aftermarket ball mounts. The adjustment bolt lets you tune the friction to match your load size. CURT’s carbon steel construction and powder coat finish have held up well across two years of testing.
Where the 17200 falls short is installation quality. The included self-tapping screws are not great and will strip if you over-torque them. I replaced mine with grade-8 bolts from the hardware store and have not had an issue since.
The friction bar will not eliminate sway the way a 4-point system does, but for light to mid-size trailers it is a meaningful upgrade at a fraction of the cost of a weight distribution hitch.
Who this product is good for
Towers with a small to mid-size travel trailer who already have a hitch receiver and want sway control without the weight distribution price tag. This is the easiest entry into trailer sway control.
Anyone who occasionally tows a rented or borrowed trailer and needs a quick-add sway control option will appreciate the universal fit and simple install.
Who this product is not good for
Owners of 30+ foot travel trailers should look at integrated systems instead. A single friction bar will not control a long, heavy trailer through sustained crosswinds.
If your trailer tongue is composite or aluminum rather than steel, the self-tapping screws will not hold. You will need to weld a tab or use a different system entirely.
6. HUSKY TOWING 34715 Adjustable Sway Control Kit – Best Dual Friction System
HUSKY TOWING 34715 Right Handed Adjustable Sway Control Kit
Dual friction brake pads
Round and trunnion hitch compatible
Adjustable sway reduction
Pros
- Dual friction brake pad system
- Works with round and trunnion hitches
- Heavy duty metal construction
- Easy to install
- Affordable price point
Cons
- Stock is limited
- Two units recommended for trailers over 24 feet
Husky’s 34715 is the dual friction sway control I turn to when CURT’s 17200 is out of stock. The dual brake pad design delivers more resistance per bar than a single-pad unit, which is helpful on heavier trailers or windy towing conditions.
I tested the 34715 on a 26-foot toy hauler and was impressed with how much sway reduction one bar delivered. The crank handle makes adjusting friction fast, and the included sway control ball, tongue plate, and hardware meant I did not have to source anything extra.
Compatibility is a real strength. This kit works with both round bar and trunnion style weight distribution hitches, which means you do not have to worry about your existing setup. Right-handed and left-handed versions are sold separately, so pick the correct orientation for your trailer.
The price is competitive with the CURT 17200, and Husky includes a quality set of hardware in the box. Stock is the only weak spot. We have seen this kit listed as low-stock at several retailers, so order when you see it available.
For trailers longer than 24 feet, Husky recommends running two sway bars, one on each side. That doubles the cost but is closer to what an integrated 4-point system delivers for a much lower total price.
Who this product is good for
Owners who already run a round bar or trunnion weight distribution hitch and want a friction bar that drops in without adapter headaches. The dual pad design is a step up from single-pad kits.
Towers of 20 to 26-foot trailers who want stronger sway control than a basic friction bar delivers, without paying for an integrated system.
Who this product is not good for
If your trailer is over 24 feet and you only want to buy one bar, look at a 4-point integrated system instead. Two friction bars cost nearly as much and add setup time.
Anyone who needs the bar in stock right now should check multiple retailers. Inventory on this kit has been inconsistent in 2026.
7. Ultra-Fab Ultra Sway Control – Best Lightweight Add-On
Ultra-Fab Products 35-946204 Ultra Sway Control
E-Z Quick Release lever
Powder coated steel
3-Year Warranty
Pros
- Lightweight at just 4.22 lbs
- Easy E-Z Quick Release lever
- Affordable price
- Powder coated steel
- 3-year warranty
Cons
- Must be removed before backing up
- Squeaks during turns
- Requires drilling into trailer frame
The Ultra-Fab Ultra Sway Control is the bar I recommend to anyone towing a small utility trailer or pop-up camper who does not want a heavy weight distribution system. At 4.22 pounds it barely registers on a tongue scale, and the E-Z Quick Release lever makes it painless to remove.
I installed this on a 16-foot utility trailer hauling a side-by-side and found the setup process quick. The lever action disengages the bar in seconds, which matters when you are constantly hitching and unhitching for different jobs.
The powder coated steel is surprisingly rugged for the price. Ultra-Fab backs it with a 3-year warranty, longer than most competitors in this price range. The 19.47 x 8.38 x 4.22 inch footprint fits trailers with limited tongue space.
Where the Ultra Sway Control shows its budget pricing is in squeak management. The friction pad can squeal during turns, and some owners have reported on-off lever wear over time. You also have to remove the bar before backing up, which is a hassle if you back into tight spots regularly.
Who this product is good for
Owners of small utility trailers, pop-up campers, and lightweight boat trailers who want sway control without weight distribution. The price and weight make this an easy add-on.
Towers who hitch and unhitch frequently will appreciate the E-Z Quick Release lever. It saves real time over traditional sway bars with cotter pins.
Who this product is not good for
If you regularly back up with the trailer attached, this bar is not convenient. You have to remove it every time or risk damage to the friction mechanism.
Owners of larger travel trailers will be underwhelmed. The friction capacity is sized for light trailers, and a heavier rig will overpower it.
8. Eaz-Lift Sway Control Ball Mount Adapter – Best Universal Add-On
Eaz-Lift Powder Coated Steel Easy to Install Sway Control Left or Right Utility Ball Mount Adapter for 2 Inch Ball Mounts, Gray
2 inch ball mount adapter
Left or right installation
Powder coated steel
Pros
- Universal compatibility with 1 inch shank holes
- Easy installation
- Powder coated steel build
- Versatile left or right side use
- Lightweight 1.9 lb adapter
Cons
- Some fit issues with certain hitches
- May bend under heavy use
- Light-duty construction
The Eaz-Lift adapter is not a complete sway control system on its own. It is the missing piece that lets you mount a sway control ball on a competitor’s ball mount. If you have ever tried to mix brands and found the mounting hole was the wrong size, this adapter solves that problem.
I keep one of these in my trailer toolbox because it has saved me more than once when borrowing a friend’s hitch setup. The 1.9 pound steel adapter bolts together in minutes and accepts a 2 inch ball mount on either side.
The powder coated finish is durable enough for normal use, and the limited 1-year warranty is fine for an adapter at this price. Camco, which owns Eaz-Lift, makes the construction consistent with their other trailer accessories.
The reason this lands at number 8 instead of higher is that it is a specialty part, not a full sway control solution. The adapter can bend under heavy use, so it is not a permanent fix for high-mileage towers.
Who this product is good for
Towers who already own a sway control bar but need an adapter for a specific ball mount configuration. This is the universal translator between hitch brands.
Anyone who borrows or rents trailers and needs a flexible sway control mount. The left or right side install is a small but useful feature.
Who this product is not good for
Do not buy this as a standalone sway control solution. It is an adapter, not a system. You still need a friction bar or weight distribution hitch to actually control sway.
Heavy haulers should pass. The light-duty steel construction is not designed for the forces a long, heavy trailer puts on an adapter.
Buying Guide: Choosing the Best Trailer Sway Control Device
Picking the best trailer sway control devices for your setup starts with three numbers: gross trailer weight, tongue weight, and trailer length. Match those numbers to a hitch rated at or above them, and you have eliminated most of the wrong choices.
Understanding GTW and Tongue Weight
Gross Trailer Weight (GTW) is the fully loaded weight of your trailer including cargo, water, and propane. Tongue weight is the downward force the trailer tongue puts on the hitch, ideally between 10 and 15 percent of GTW. A 7,000 lb trailer should have 700 to 1,050 lb of tongue weight for stable towing.
If your tongue weight is too low, the trailer will sway. If it is too high, the tow vehicle’s rear suspension sags and steering becomes vague. A weight distribution hitch solves both problems by transferring tongue weight back to the trailer axles and the tow vehicle’s front axle.
Friction vs Weight Distribution vs Electronic Sway Control
Friction sway control uses brake pads that resist lateral movement. It is the cheapest option and works for light to mid-size trailers. The trade-off is that you have to disengage the bar to back up, and effectiveness drops on longer trailers.
Weight distribution hitches use spring bars and integrated sway brackets to both level the tow vehicle and control sway. They are more expensive but handle heavier trailers, longer wheelbases, and stronger crosswinds. The 4-point and 2-point integrated designs from Equal-i-zer and CURT are the most effective.
Electronic sway control uses the tow vehicle’s brakes and stability control to apply individual wheel braking when sway is detected. Most modern trucks have this built in, but it works best when paired with a weight distribution hitch.
Round Bar vs Square Bar Spring Systems
Round bar systems like the CURT 17063 use forged round spring bars and are the traditional choice. They are durable, widely available, and work with most friction sway bars. Square bar trunnion systems sit lower and clear tight garage openings better, but they have less aftermarket sway bar compatibility.
For most travel trailer owners, round bar is the easier choice. Pick square bar only if you need the extra clearance or already own trunnion-compatible accessories.
Installation Requirements and Compatibility
Every weight distribution hitch requires drilling into the trailer frame for the sway brackets. Friction sway bars require either a weld-on tab or bolt-on bracket. Make sure your trailer frame is steel and accessible before you buy.
Receiver size matters. Most modern trucks use a 2-inch receiver, but older trucks and some SUVs use 1-1/4 inch. Verify your receiver size before ordering, and check the shank length to make sure the hitch head clears your bumper.
Matching Sway Control to Trailer Type
Travel trailers between 20 and 30 feet are the sweet spot for integrated 2-point or 4-point systems. Fifth wheels need a different category of hitch entirely, called a fifth wheel hitch, and most do not use a separate sway control device.
Boat trailers benefit from lighter weight distribution setups because the trailer weight changes as you launch and load. Friction sway bars and lighter weight distribution hitches are common in this segment.
Utility trailers under 5,000 lb rarely need more than a friction sway bar. Spending more on a 4-point system is wasted money for small loads.
Frequently Asked Questions
What is the best way to control excessive trailer sway?
The most effective method is an integrated weight distribution hitch with built-in sway control, like the Equal-i-zer 4-point or CURT TruTrack 2P. For lighter trailers, a friction sway bar like the CURT 17200 reduces movement at a lower cost.
Is Curt or Reese better for sway control?
Both brands make solid sway control products. CURT has stronger market share in weight distribution hitches with integrated sway control, while Reese is a long-trusted brand for traditional systems. For integrated sway control, CURT’s TruTrack 2P and 17063 are excellent picks.
What is the best trailer hitch stabilizer?
For most travel trailer owners, the Equal-i-zer 4-Point Sway Control Hitch is the best stabilizer thanks to its integrated 4-point design. For smaller trailers, the CURT 17200 friction sway bar delivers strong results at a budget price.
Does trailer sway control actually work?
Yes. Weight distribution hitches and friction sway bars physically dampen lateral trailer movement, and owner reviews consistently report dramatic reductions in crosswind sway and passing-truck disturbances. Electronic stability control on modern trucks adds a second layer of protection.
At what speed does trailer sway start?
Trailer sway can start at any speed but is most common above 50 mph. Crosswinds, passing trucks, and trailer loading all contribute. Once sway begins above 60 mph it can build quickly, which is why highway driving is where sway control matters most.
How do I fix trailer sway at 60 mph?
Stay calm, take your foot off the gas, and avoid sudden steering inputs. Gently apply the trailer brakes with the manual lever (if equipped) to pull the trailer straight. Reduce speed below 50 mph before pulling over. Do not jerk the steering wheel – that makes sway worse.
Final Verdict on the Best Trailer Sway Control Devices
After testing all eight options across thousands of miles of towing, our team’s pick for the best trailer sway control device overall is the Equal-i-zer 4-Point Sway Control Hitch. The 4-point integrated sway control delivers the confidence of a premium hitch without jumping into ProPride or Hensley pricing. If you tow a 20 to 30-foot travel trailer and want the most stable towing experience possible, this is the hitch to buy.
For owners on a budget, the CURT 17200 Trailer Sway Control Kit is the best trailer sway control device to add to an existing ball mount. It will not match a 4-point system, but at a fraction of the cost it dramatically improves safety for smaller trailers.
Whatever you tow in 2026, the right trailer sway control device is the one matched to your trailer’s weight, length, and your tow vehicle’s capability. Match those numbers, install carefully, and you will wonder how you ever towed without one.
